13 Claims. 1

This invention relates to improvements in tools for splicing the ends ofline or strand material.

The primary object of this invention is the provision of a relativelysimple practical tool which may be manufactured at relatively low cost;the purpose of which is to facilitate the splicing or knotting of theends of flexible line or strand material such as gut, nylon, yarn,threads, etc.

A further object of this invention is the provi sion of an improved linesplicing tool which may be utilized for the purpose of knotting the endsof line material, with knots such as described in U. S. Patent2,488,414.

A further object of this invention is the provision of an easily handledportable tool which can be used by fishermen and others for the purposeof Splicing flexible strands of line material together with non-slipknots.

Other objects and advantages of the invention will be apparent from thefollowing detailed description.

Figure 14 is a front elevation of a knot modified with nickel orchromium, etc. handle portion 1 l and an upper portion l2 wider splicingtool including many of the characteristics of the tool of Figure 1.

Figure 15 is an edge elevation of the tool of Figure 14.

In the drawings, wherein for the purpose of illustration are showndifferent forms of the invention, the letters A and B may represent thepreferred and modified forms of tools respectively shown in Figures 1and 14. In each of these forms an improved knife arrangement C isprovided having similar characteristics.

The tool A comprises an elongated fiat body portion frame structure Illof copper, brass, stainless steel. It may be of base metal which isplated It includes a lower than the handle portion. The latter flares atopposite sides 13 and H! in a widening relation. The body I0 ispreferably of uniform thickness thruout its length. At the extremehandle end. it is provided with an aperture IE to facilitate handling.The top marginal edge I6 is convexly arcuated, or in lieu thereof thesame may slope downwardly convergently from the medial axial line of thebody.

Line or strand clamps 20 and 2! are provided upon the upper end of thebody portion In. They are relatively strong spring clamps and may takevarious forms. clamp includes a main clamping strip portion 22 providedwith parallel right angled attachin ears 23 which lie at opposite sidesurfaces of the body portion l0 and are riveted to the latter at 24. Theclamping strip 22 extends in clos spring engaging relation with the topmargin [6 of the body portion I0. Spaced from the ears 23 are a secondsmaller pair of ears 2B in engaging relation at each side of the bodyportion 10; these ears 25 having merely frictional sliding contact withthe side surfaces of the body portion 10. Th extreme spring clamping tip30 of each of the clamps 20 and 2| is slightly turned upwardly from thetop edge of the body portion 10. The tip ends 30 of the clamps 20 and 2|lie in close relation but are spaced at 3| so that the strands ofmaterial may be readily slipped under the tip ends 30 and beneath theclamping portions.

The body top I 2 along its longitudinal, axial line is provided with astrand threading aperture immediately below or adjacent to the clamps 2nand 2|. A second pair of strand clamps 45 and 46 are provided upon thebody portion ID at opposite side surfaces of the latter. They consist ofspring clamp arms riveted by a single rivet 4! along the medial axialline-of the tool, but

In the instance shown, each the spring clamping arms 45 and 65 extendlaterally in opposite directions; preferably convergently downwardtoward the handle end of the tool.

Referring to the knife structure C, the same includes a button-likeknife disc 50 secured in sliding relation upon one side surface of thebody portion ill at the lower end of the upper portion [2. The meanswhich secures it preferably consists of a screw or bolt 5| threaded thrua nut 52. The latter overlies the outer surface of the button 50 and hasan extension projecting thru the central opening of the cutting disc 56.The body portion I0 is slotted at 53 to receive the attaching means forthe cutting disc and this facilitates sliding of the cutting discaxially along the body portion H), as is quite obvious. The body portionI0 is provided with a selection of openings 56, 51 and 58 which may becounter-recessed at one side of the tool body H3. The recessed side isadapted to receive the knot end of the strands and the loose ends arethreaded thru the opening and project from the side along which theknife disc slides.

strands l0 and H to be spliced are positioned 'so as to bypassoverlapping ends.

The end portion of strand H, designated at'll is-placed under theclamping tip 36 of the clamp and the loose-end Hi of the strand or line'10 is placed under the tip end of the other clamp 2|. The length of theloose ends of the strands or lines may suit convenience since all slackis retrieved in the pull-up operation.

With the tool resting loosely in the hand, both thumbs of the operatorshands and foreflngers are free for use in wrapping of the ends in eitherdirection, at least two full turns over and under the main body lineadjacent thereto. This is shown in Figure 6 of the drawings where theloose end (I is shown as having been wound over and under the main lineportion of the adjacent strand l9 and then fed downwardly thru theV-shaped opening 80 and thru the threading opening or aperture 60. Theloose end is then clamped under the spring clamp at the opposite side ofthe body Ill.

The above operation is repeated with the remaining loose end w the samebeing wound as above described around the mainline l l as shown inFigure '7 and then threaded downwardly thru the opening loop 86 and thruthe threading aperture 36. It is finally secured under the spring clamp26. Care should be taken to guard against feeding the end of the secondwrapping thru the loop of the first. The main lines '30 and H are thentaken in the hands of the operator, as shown in Figure 9 and toolpermitted to hang loose. Inasmuch as the loose ends l0 are held by theclamps 45 and 46 the operator can urge the knot into place by pullingupon the lines, as is quite obvious. The loose ends are then freed fromthe keeper springs and the operator cansnub the knot a little tighterwith his thumb nails. The loose ends are then threaded thru 'the opening'51, or the other openings, depend- The action of the knife disc is suchthat .itmay be positioned in the lower end of the slot ing upon thegauge of the line. The operator grasps the loose ends as shown in Figure12 and the knot is pulled into the recessed side of the aperture, asclose as desired. The thumb button is then fed to the position in Figure13 and this severs the loose ends. This produces a knot, such as shownat 90 in Figure 10 of the drawings.

To produce another type of knot, the lines are manipulated precisely thesame as shown in Figures 5 and 6. However, instead of continuing asshown in Figure '7, the second loose end '19 is wrapped around the mainstrand II and threaded upwardly thru the loop opening from below. It isthen taken in the fingers and carried across over the top of a strandforming the loop (either one) and then is extended thru the aperture 40and clamped at the opposite side. The knotting operation is the same asabove described and shown in Figure 9. This will produce the type ofknot shown at 9| in Figure 11 where the loose ends extends in oppositedirections instead of parallel.

Insofar as applicable, the same reference characters are applied to themodified form of invention as above described for the preferred form A.The principal departure from the preferred form is that the upperportion l2 of the body or frame structure of the tool is provided withintegral spring clamping arms 20* and 2| which extend toward each otheralong the sloping edges 16* and I6 of the top margin of the tool. Thetip clamping ends of the clamps are slightly upturned away from theedges l6 and l6 to provide entrance openings for the slipping of thestrands of material under the clamping ends or tips 3D. It is quiteobvious that the knot tying operation can be accomplished with the toolB in the-same manner as above described for the tool A.

Various changes in the shape, size and arrange ment of parts of theimproved appliance may be made, as well as departure from the steps ofmanipulating the various strands of material in the splicing of knotsthereupon, without departing from the spirit of the invention or thescope of the claims.
